OLIVER W- j cum WATERIOWN, NEW YQRK- I srrmr iuannnn.

To all whom it may, concern; :1 I Be it known that I, On vnn CnR rIs, a; i n f h U t d, States-r s d ng a lflt tQ n, u y f fierso dfitat oflNew Yoilgxhave invented certain'new and useful Improvements in Strip- Markers, f W c -t e ell w g'is pe c tion. 7 a,

The invention relates to such improvements and consists in the, novel construction and combination of parts hereinafter dee. scribed and subsequently claimed, o B i he mayb had, touthe ec mpanyr. ing drawings, and the reference, characters a ke hereon, which f r a Part o t is peq e biQh-t S milar charac e s refer to im l r pa tsl nt sev ral figures herein- Figural; of the drawingsi-saview inside elevation of my improved strip marker.- Fig. 2 isa top plan view of the same, partly. broken away and partly shown in section Fig. 3 is a front elevation of thesamey Pa tly b ke away a pa t y' how section, Fig. 4 is ajverticalcr0ss section taken on the broken line Jr-tin Fig. 2, Fig;

T e p nc pa obj of; the inventi n sto. automatically. apply to a strip; of flexible material, as the same is'fed over a -adrum of constant diameter, marks at regulanin intervals:Qfvariable length at the will ofthe operator, which marks indicate points at which the strip can be severed to form'see' tions ofequal length adapted for various USES, 1 v z I H The apparatus shown in the drawings is particularly adaptedfor thus markinga strip, sections of whiehfare to be severed or stitchedyupon underdrawers to form waist bandstherefolm j 7,

In carrying out my invention .Lemploy an ordinary crayon or lead-pencil in combie nation with a drum of constant diameter over which the strip .is fed, with means for supporting the pencil and causing it to en- -;gage the strip at regular intervals'in; ac-s Specification of Letters Patent.

The "drum ofconstant diameter, and has on its periphery a series of spurs, 7, which engage, the strip, and cause thestrip to positively rotat the drum as the strip is fed thereover. The, drum, g3, is fixed upon a sleeve, 8, by; means of an internal dia:

phragm, 9, withinthe drunnsaid sleeve, 8, beingniounted/torotate freely upon a horizontalshaft 10, which is fixedly m unted,

feathered upon the sleeve, 8, to movelongitudinallythereof as a unit, while rotating in connection with said sleeve and the drum, 3.

the feather, 16, on the sleeve, 8.

' The yoke, 12, is fixed upon the innerend of a; gear-rack, 1,7, recipnocatory in a slide-.

way,18, ontthebracket, 2, in a vertical plane passing through the axis, of the vdrum. The. teeth on the rack,*17,-are engaged by a pinion,i19, fixedupon a shaft, 20, which extends perpendicularly to the rack, 17, and

is 'rotatively; mounted in, a vrticallyswing-Q ing-fralne, 21, pivoted at 22, upon the bracket, 2.,The outer end of the shaft, 20,

has fixed: thereonia s'piralcam, 23, the per,

riphery of which is provided: with a series of notches,24=', adapteditolseverally receive is a knife-edge, 25,which is fixedly mountedon an arm, -26, projecting from the 29,which meshes with a gear-wheel, 30, fix

upon a shaft, 22,which forms the pivot for the vertically swinging-frame,'21.

'. The crayon or pencil, 31, is clamped'upon the end of an arm, 32, projecting from a slide, 33, which slide-is adapted to reciprocate Vertically in a slideway, 3 1:, on-an upward extension of the bracket, 2.

The slide, 33, has near its lower end an offset and a coil-spring, 36, is yieldingly confined between said offset, 35, and the topwall of a recess in the slideway, 34,*tend ing to yield-ingly hold the slide, 33, depressed. The slide, 33, also has upon its lower end a follower-roller, 37, adapted to 'engagea cam, 38, fixed upon the shaft, 27,

which cam is formed 'with a notch, 39,

' adapted topermitthe follower, 37, and slide,

33,to drop sufficiently to permit the pencil to engage and make a mark uponthe strip onthedrum' a The notches,"24c, in the periphery of the spiral cam, 23, are spaced apart to correspond with different lengths of strip to be indicated by'marks; of the penci1,-31; and

the spiral form of said cam is such that as.

the cam is rotated tobring its portions of larger diameter opposite the knife-edge, 25,

it will through the shaft, 20, pinion, 19,

rack, 17, and yoke, 12, slide the gang of gears along the sleeve, 8, to bring one of.

the larger gears, 11, opposite the gear-wheel, 28, while at the same time the swingingframe, 21, will, by engagement of the surface of the cam, 23, with the knife-edge, 25,

be supported in a sufliciently higher position to permit the gear, 28,'to properly engage and mesh with the proper gear, 11. It will thus be seen that by'properly proportioning the various gears, 11, with relation to the diameter of the drum, 3, and the positions of the notches, 24, a greater or less angular movement of the drum, 3, can be caused to produce a uniform angular movement of the shaft, 22, and thepencil-actuating cam,-'38. For example, when sections of considerable length are to be marked on thestrip, one of thesmallergears, 11, is caused to mesh with the gear, 28, said gears being in such ratio to each other that when the drum has trav- I T eled a distance, measured circumferentially,

equalto the length of the strip-section to be marked, one complete rotation will be im-v parted to the shaft, 22, and-cam, 38; and for successively shorter lengths of strips to be marked, successively larger gears, 11, will be caused'to mesh with the gear, 28.

I have shown the various lengths of strip indicated by numerals on the face of the cam, 23, adjacent to the respective notches, 24.

, By. the, use of this invention, I avoid the necessity for changing the diameter of the drum for the marking of strips into sections of different lengths.

7 What I claim as new and desire to secure by Letters Patent ise 1. 'In' a strip-marker, and in combination,

a rotatory drum; a frame movable toward and from the axis of the dru'm; a shaft rotatively mounted'in said frame; a'pair of gear-elements, one mounted upon said shaft,
